In today’s information age, how to carry out the accurate information communication is a crucial issue in the field of communication, which is widely used in civil and military fields. Frequency hopping communication system is a typical spectrum communication system, it is in military communication, mobile communication, computer wireless data transmission and wireless LAN and other fields have a very wide range of applications, has become the current short wave communication is one of the important development directions. In this paper, we introduce a design of frequency hopping communication system based on Matlab. Through the frequency hopping communication system the simulation research and theoretical analysis, to achieve the desired results.
